Description

Technical Field

[0001] The present application relates to the technical field of construction material transportation, and in particular to a construction site material transportation device based on BIM technology. Background Art

[0002] BIM technology refers to a building information model established based on various information of construction projects. It can fully predict problems in the construction process and achieve the best results for the construction project. In recent years, BIM technology has been widely used in construction projects. This technology can be used to construct a building information model and realize refined management, thereby improving the quality of construction projects.

[0003] B1M technology can store information modules related to construction materials and equipment in the plane layout, and through the use of Internet technology, the staff can query the information of the required materials and mechanical equipment at the first time, and can compare whether the materials and mechanical equipment required at the construction site are consistent, to ensure that all materials and equipment can be used reasonably. It should be noted that in the existing technology, although BIM technology can be used to dispatch the materials required for the construction site in a timely manner, this is limited to supplementing and borrowing the missing materials. When the materials are transported to the construction site, they are generally piled on the ground. When needed, the materials are transported to the required floor through the material hoist. During the transportation process, the materials are first loaded onto the material hoist, and then transported to the designated floor by the material hoist, and then unloaded. After that, the material hoist can continue to descend to the ground to continue to transport materials, which is inefficient. In addition, since the material hoists are installed in fixed places, they can only be transported vertically, and the number is limited, while the area of ​​the floor is large, after the materials are transported to the designated floor, they must be manually transported to the designated location again, which is time-consuming and labor-intensive, thereby reducing the construction efficiency.

[0004] To this end, we propose a construction site material conveying device based on BIM technology to solve the above problems. Summary of the invention

[0005] In view of the problems existing in the prior art, the present application aims to, after the material box is transported longitudinally to the designated floor by the car, also drive the material box to move horizontally, and quickly transport the material box to the designated location where the material is required. In the process of the horizontal movement of the material box, the car can also take away the empty material boxes on other floors and re-transport the materials, thereby improving efficiency. Compared with the prior art, a construction site material conveying device based on BIM technology is provided. By setting a reversing connecting piece, after the material box is transported longitudinally to the designated floor, the material box is connected to the moving piece through the reversing connecting piece, and the material box is driven to move horizontally by the moving piece to realize the change of conveying direction. In the process of the horizontal movement of the material, the car moves to the floor with the empty material box, loads the empty material box on the floor into the car, and then drives the empty material box to descend to load the material again and transport it. While the material is being transported on one floor, new material is loaded again and transported to other floors, so that the material transportation of multiple floors can be carried out simultaneously, thereby improving the material transportation efficiency.

[0020] Furthermore, a limit support block is arranged inside the car, and a guide surface is arranged on the limit support block.

[0021] Compared with the prior art, the advantages of this application are:

[0022] (1) By setting a reversing connecting piece, the motor is started to drive the bevel gear 2 to rotate, and the rotation of the bevel gear 2 drives the bevel gear 1 and the spur gear to rotate. The rotation of the spur gear drives the racks on both sides to move, and the movement of the rack drives the mounting block and the connecting block to move until the connecting groove on the connecting block moves to the outside of the electric slider, so that the electric slider is inserted into the connecting groove. Then the electric push rod is started, and the output end of the electric push rod extends to push the slider 1 to move in the slide groove 1. During the movement of the slider 1, the inclined surface 1 squeezes the inclined surface 2 of the slider 2, thereby pushing the slider 2 to move in the slide groove 2, so that the sliders 2 on both sides move into the clamping holes on both sides of the electric slider, thereby connecting the material box and the electric slider together to achieve a change in the transportation direction.

[0023] (2) During the lateral movement of materials, the car will move to the bottom of the floor with an empty material box, and then the material box that has been unloaded on that floor will move toward the lifting shaft until it is above the car. At this time, the car continues to move upward so that the empty material box can enter the interior of the car. After that, the output end of the electric push rod will shrink, driving slider 1 and slider 2 to reset, thereby driving slider 2 to disengage from the latching hole, and then start the motor to reverse, driving the mounting block and the connecting block to move in the opposite direction and shrink and reset, so that the electric slider will disengage from the connecting groove. At this time, the material box is separated from the electric slider, and the car can drive the material box to descend to the bottom of the lifting shaft to reload the material and transport it again, so that new material can be loaded again and transported to other floors while the material is being transported on one floor, so that the material transportation of multiple floors can be carried out simultaneously, which greatly improves the time utilization of the device and thus improves the material transportation efficiency.

[0024] (3) By setting a transfer piece, the electric slider starts to move in the slide rail, which can drive the connected material boxes to move on the slide rail, thereby driving the material boxes to move quickly to the designated location.

[0025] (4) By setting a reset member, when slider 1 moves toward the outside of slide groove 1 to reset, slider 1 gradually leaves slider 2. After slider 2 loses the squeezing effect of slider 1, it drives slider 2 to reset under the action of the compressed spring force, thereby driving slider 2 to disengage from the clamping hole, thereby realizing the separation of the material box and the electric slider.

[0026] (5) By arranging matching inclined surface 1 and inclined surface 2 on the side where slider 1 and slider 2 are close to each other, when slider 1 moves toward the inside of slide groove 1, under the transmission action of inclined surface 1 and inclined surface 2, slider 2 will be squeezed to move out of slide groove 2 and inserted into the snap-in hole, thereby realizing quick connection between the material box and the electric slider.

[0027] (6) By arranging a rubber block and a rubber ring in the slider 2 and the clamping hole respectively, when the slider 2 is inserted into the clamping hole, the rubber block and the rubber ring squeeze each other, so that the connection between the slider 2 and the clamping hole is tighter, thereby making the connection between the material box and the electric slider more stable.

[0028] (7) By setting a limit support block inside the car and setting a guide surface on the limit support block, the limit support block can support the bottom of the material box. When the material box descends into the car, the guide surface can guide the reversing connector to be located between the limit support blocks, thereby limiting the position of the material box, preventing the material box from shaking during transportation, and enhancing the stability of the material box.

[0029] (8) By setting doors and baffles on both sides of the car, when loading materials, the doors are opened and the materials are loaded in the material box. After the materials are transported to the designated location, the baffles can be opened to unload the materials. During the transportation process, the doors and baffles can limit the material box to prevent the material box from sliding and shaking in the car, making the material box more stable during transportation.

[0030] (9) By providing a protective shell on the outside of the reversing connector, the protective shell can protect the reversing connector and prevent sand and stone impurities from falling into the reversing connector, thereby ensuring the normal operation of the device.

When the slider 1 410 moves toward the inside of the slide groove 1 407, under the transmission action of the inclined surface 1 and the inclined surface 2, the slider 2 411 will be squeezed to move out of the slide groove 2 408 and inserted into the clamping hole 503, so as to realize the quick connection between the material box 3 and the electric slider 502.

[0044] Specifically, the motor 414 is started to drive the bevel gear 2 415 to rotate, and the rotation of the bevel gear 2 415 drives the bevel gear 1 413 and the spur gear 412 to rotate. The rotation of the spur gear 412 drives the racks 416 on both sides to move, and the movement of the racks 416 drives the mounting block 404 and the connecting block 405 to move until the connecting groove 406 on the connecting block 405 moves to the outside of the electric slider 502, so that the electric slider 502 is inserted into the connecting groove 406, and then the electric push rod 409 is started, and the output end of the electric push rod 409 is extended to push the slider 1 410 to move in the slide groove 1 407. During the movement of the slider 1 410, the inclined surface 1 squeezes the inclined surface 2 of the slider 2 411, thereby pushing the slider 2 411 to move in the slide groove 2 408, so that the sliders 2 411 on both sides move into the clamping holes 503 on both sides of the electric slider 502, thereby connecting the material box 3 with the electric slider 502 to achieve a change in the transportation direction.

[0046] Specifically, the electric slider 502 is started to move in the slide rail 501, which can drive the connected material boxes 3 to move on the slide rail 501, thereby driving the material boxes 3 to move quickly to the designated location.

[0047] Working principle: First, the car 2 is lowered to the bottom of the lifting derrick 1 by an elevator (the elevator is a prior art, not shown in the figure, and will not be explained in detail here), and the required materials are loaded into the material box 3, and then the elevator drives the car 2 to move vertically upward to transport the material box 3 to the designated floor;

[0048] Then, the motor 414 is started to drive the bevel gear 2 415 to rotate. The rotation of the bevel gear 2 415 drives the bevel gear 1 413 and the spur gear 412 to rotate.

[0050] During the lateral movement of the material, the car 2 will move to the bottom of the floor with the empty material box 3, and then the material box 3 that has been unloaded on this floor will move toward the lifting shaft frame 1 until it is above the car 2. At this time, the car 2 continues to move upward so that the empty material box 3 enters the interior of the car 2, and then the output end of the electric push rod 409 contracts, driving the slider 1 410 to move to the outside of the slide groove 1 407 to reset, and the slider 1 410 gradually leaves the slider 2 411. After the slider 2 411 loses the squeezing effect of the slider 1 410, it drives the slider 2 411 to reset under the elastic force of the compressed spring 603, thereby Drive the slider 2 411 out of the locking hole 503, and then start the motor 414 to reverse, drive the mounting block 404 and the connecting block 405 to move in the opposite direction, shrink and reset, so that the electric slider 502 is out of the connecting groove 406.
